What is Trichloroethylene?
Trichloroethylene (CAS 79-01-6), commonly abbreviated as TCE and sold under trade names such as Trilene and Triclene, is a chlorinated solvent used primarily for degreasing metal surfaces.
Where is Trichloroethylene used?
- Metal fabrication and electronics: vapor degreasing to remove oils, greases and machining residues before coating or assembly
- Plastics and polymers: reaction medium and chemical building block in PVDF and other fluoropolymers
- Printing and packaging: carrier solvent for inks and adhesives
- It serves as a feedstock in the synthesis of HFC-134a refrigerant.
Commercial specifications
- Clear liquid in drums, IBCs and bulk tanker quantities
- Specifications aligned with ISO and ASTM standards for industrial solvent purity
